בַּעַל קֶרִי – מְהַרְהֵר בְּלִבּוֹ וְאֵינוֹ מְבָרֵךְ, לֹא לְפָנֶיהָ וְלֹא לְאַחֲרֶיהָ. וְעַל הַמָּזוֹן – מְבָרֵךְ לְאַחֲרָיו, וְאֵינוֹ מְבָרֵךְ לְפָנָיו. רַבִּי יְהוּדָה אוֹמֵר: מְבָרֵךְ לִפְנֵיהֶם וּלְאַחֲרֵיהֶם.

The Baal Keri mentally reads the Shema in his heart, but doesn’t need to do the same for its blessings, not for its preceding blessings and not for its following blessings. And for food: he blesses the after-blessing, but not the preceding-blessing. Rabbi Yehudah says: he even recites the preceding and following blessings.
